To all whom t may concern.'

` Be it known that l., JOHN W. TRIMBLF., .a citizen of the United States, residing at Amos, in the county of Vernon, State of Missouri, have invented certain new and useful Improvements in 1Combined Disk Listers and Planters; and lldo hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to'which it ppertains to make and use the same.

This invention relates to combined disk listers and planters and has for an object to provide a device of this character which will prepare a more effective seed bed in ad'- vance of the planter boot than prior devices of this character.

The purpose is to provide a machine of this typewhich will irst open awsutioienlly deep listing trench or furrow, then loosen up the sub-soil along the center of the furrow bottom, then form a ridge by pulverizing the 'earth at the sides of the center of the trench and throwing it toward said center, then open a shallow furrow for the seed along the top of the ridge, then deliver the seed to `proved machine.

Fig. 2 is a plan view.

Fig. 3 is a. diagrammatic plan showing the relative location of the various ground working parts of the device,

Fig. 4 is a diagrammatic view showing the development of the seed bed.

Referring now to the drawing in which like characters of reference designate simi-- lar parts, l0 designates a beam which is supported near the front end by a turning axle 1l equipped with ground wheels 12, and is supported near the rea-r end by a rear ground wheel 13 the tread of which 1s concave as shown at le, this wheel forming a packer wheel the operation of which will be hereinafter more fully explained.

A colter 15 is secured to the front end of the beam, and depending from the beam in rear of the axle is a hanger .1G that carries a pair of forwardly converging furrow opener disks 17 that open the furrow as shown at el in Fig. 4. Also carried on the standard between the disks is a. suhsoil plow 18 that perates to loosen up the subsoil of the furrow as shown at B in Fig. ll. Depending from the beam in rear of the subsoil plow is a hanger 19 that carries a pair of rearwardly convergent lister disks 20 which cut the soil from the lower concave parts of the main furrow, loosen and pulverize it and deposit it over the soil loosened by the plow 18 to produce a ridge of loose subsoil as shown at C in Fig. 4. A corn hopper 21 is carried on the beam in rear of the lister disks and communicates with a seed boot 22 which opens the top of the loose ridge of subsoil and drops the seed therein, as shown at l) in F ig. l. The seed dropping mechanism is operated by a chain drive 23 from the axle, or

otherwise to drop the seed at spaced intervals apart. Finally the concaved rim of the packer wheel follows 'the seed boot and firmly packs down the ridge upon the dropped seed as shown at E in Fig. Ll.

By following my method of acting on the soil at the bottom of the lister furrow there is formed, as shown in the diagrams in Fig. fl, a well marked longitudinally extending elevated ridge -of pulverized soil in which the seeds lie, the elevation oflthis ridge above the horizontal plane where the curves of the main furrow walls meot remaining even after the seed has been packed. fand l be- L tom.: o1' di itl of plomo; than is orio? lovcos of tor' .i of til@ soil, for plzmt i :tccvozdiiwo method; i to t. initial fom-ow is opened io lilith 'tho seed plmitod und vich of several succo vo cultiis partially filled outil finally il W if: u'oughi; up to tho forming fi, suoti iii. and thou oooxriiig l: imploowil N li :l Yo 4 am?, planting, muli mld, no ototnvm sliding; (lon-- mttfmis.4 or b1 fi;
